Comparison of Different Softening Methods for Patchouli and Optimization of Processing Technology
摘要
Abstract
[Objective] To optimize the best processing technology of patchouli,and determine the process parameters for the application of the actual production.[Method] Separate investigation on processing technology of patchouli stems and leaves was conducted by vapor phase displacement type medicine moistening machine.With the characters of processed products,alcohol soluble extract yield and content of patchouli alcohol as indexes,the optimal processing technology of patchouli stems were obtained using single factor experiment.Then using orthogonal design L9 (34) to study the effects of cutting length,drying temperature and drying time on the processing technology of patchouli stems.With the content of the water,patchouli alcohol and volatile oil as indexes,processing technology of leaves was optimized.[Result] The optimal processing technology of patchouli stems:The stem is washed once in water,put the patchouli to the vacuum vapor replacement,and set as 50℃ run 2 h,then remove,and cut into sections (about 4mm),and then dry 1.5 h at 50℃.The optimal processing technology of patchouli leaves:The leave is washed once in water,and then dry 135 min at 50℃.[Conclusion] After the process validation,it is stable and reliable.The processing technology of patchouli prepared by the method can be used in practical production.关键词
